Astrain gauge with a 5 mm gauge length gives a displacement reading of 1.25 um. calculate the stress value given by this displacement if the material is structural steel.

stress  = 50MPa

Explanation:

given data:

Length of strain guage is 5mm

displacement

stress due to displacement in structural steel can be determined by using following relation

where E is young's modulus of elasticity

E for steel is 200 GPa

stress  = 50MPa

the equation above shows how temperature f, measured in degrees fahrenheit, relates to a temperature c, measured in degrees celsius. based on the equation, which of the following must be true?

a temperature increase of 1 degree fahrenheit is equivalent to a temperature increase of

5

9

degree celsius.

a temperature increase of 1 degree celsius is equivalent to a temperature increase of 1.8 degrees fahrenheit.

a temperature increase of

5

9

degree fahrenheit is equivalent to a temperature increase of 1 degree celsius.

a) i only

b) ii only

c) iii only

d) i and ii only

answer:

explanation:

assault rifle is a rapid-fire, magazine-fed rifle designed for military use. it is a shoulder-fired weapon that allows the shooter to select between semi-automatic (requiring you pull the trigger for each shot), fully automatic (hold the trigger and the gun continuously fires) or three-shot-burst modes.
